operation
Optoisolated 4mA to 20mA Process Controller
Figure 5 shows how to use an LTC2630HZ to make an
optoisolated, digitally-controlled 4mA to 20mA transmit-
ter. The transmitter circuitry, including optoisolation, is
powered by the loop voltage which has a wide range of
5.4V to 80V. The 5V output of the LT3010-5 is used to
set the 4mA offset current and VOUT is used to digitally
control the 0mA to 16mA signal current. The supply cur-
rent for the regulator, DAC, and op amp is well below
the 4mA budget at zero scale. RS senses the total loop
current, which includes the quiescent supply current and
additional current through Q1. Note that at the maximum
loop voltage of 80V, Q1 will dissipate 1.6W when IOUT =
20mA and must have an appropriate heat sink.
ROFFSET and RGAIN are the closest 0.1% values to ideal
for controlling a 4mA to 20mA output as the digital input
varies from zero scale to full scale. Alternatively, ROFFSET
can be a 365k, 1% resistor in series with a 20k trim pot
and RGAIN can be a 75.0k, 1% resistor in series with a 5k
trim pot. The optoisolators shown will limit the speed of
the serial bus; the 6N139 is an alternative that will allow
higher data rates.
